#1202417 fixed - Customize left-click in library action
Do not fake a Return key press to expand/collapse a library sidebar item. Fixes Bug #582503.
Add Marcos Cardinot to the credits.
add pre-push script to build and run tests

this hook can be activated with
`ln -s ../../scripts/git-hooks/pre-push.sh .git/hooks/pre-push`

This way git will only push if the test-suite passes. Be aware that this
will trigger a build with `scons test=1 -j$NUM_CORES` each time you
push. Also I only tested this on linux.
add test_data dir to gitignore
Fix effect tests. They broke after some control and behavior changes.
Revert "Fix effect tests. They broke after some control and behavior changes."

I accidentally committed a bunch of local changes.

This reverts commit 9e8575bd3fff1c9427d5f189683c3b57adc2ec0d.
Fix effects tests that broke after some control and behavior changes.
Add playlist and crate track counts and durations in the library sidebar.

Fixes Bug #991938 and Bug #1014951.
Move `Track load action` box in the library preferences a bit up so that all options related to the internal library are grouped together. Tiny changes to the labels to they match existing strings and are auto-translated by the translation memory. Also add a translator comment.
Update translations template after latest controller wizard changes.  Found 1468 source text(s) (213 new and 1255 already existing)
Set step/small-step for pitch knob to be a full-step and half-step (semitone).
Set the default for the delay potmeter to zero so resetting it clears the delay
rather than picking the half-way point.
Add TODO to support soft-takeover for setParameter/getParameter.
Disable translations for a few fields that are just placeholders.
